Justin Beiber and baby sister Jazzy are lighting up the Internet with a video of them singing Home for the Holidays 2011, but Beibs has revealed he never did believe in Santa Claus.

You can blame his mother for that.

Bieber's mother didn't give him the chance to believe in Santa Claus, he explained.

My mom always told me there wasn't a Santa. That was her logic. She thought if I grew up knowing about Santa then finding out he wasn't real, that it would be like she was lying to me, Bieber said.

Bieber said his mother thought he wouldn't believe in God if she told him Santa was real, only later to found out she was lying. Yet, Beiber said he didn't spoil it for friends who did believe in Santa.

I didn't tell my friends or ruin it for anyone - I was a good kid!

Christmas was still a time for presents for the Biebers, however.

We played a game on Christmas Day where everyone brought a girl gift and a boy gift. You roll the dice and if you get doubles, you get to pick a present and if you don't, it's the next person's turn. One time I really wanted a Game Boy but I ended up with pots and pans, which was disappointing.

Bieber just aired a Home for the Holidays concert special in Toronto. See the video below of Bieber singing Home for the Holidays with Jazzy:
